Abstract

Known systems based on stereoscopic video coding and video decoding code with inadequate efficiency because the left-hand picture and the right-hand picture are coded and decoded independently of one another by means of the encoders present in the system. As a result of providing one encoder with switching means to which a signal representing the left-hand picture and a signal representing the right-hand picture are fed, said encoder is able to base the prediction either on the left-hand picture or the right-hand picture, and this improves the prediction and, consequently, the efficiency of the coding. As a result of designing the switching means, according to one embodiment, for the adjustment of the ratio of the signal representing the left-hand picture and the signal representing the right-hand picture and for the subsequent addition of the two adjusted signals, a still greater advantage is achieved in the prediction with the correct ratio, and this results in a further improvement in the efficiency of the (total) coding. <IMAGE>
